Medicare Part B Coverage for Durable Medical Equipment

Medicare durable medical equipment coverage helps millions of beneficiaries access essential health devices every year. Part B covers items like wheelchairs, hospital beds, oxygen equipment, and walkers that doctors prescribe for home use. For many older adults and people with disabilities, these devices make independent living possible.

However, understanding what qualifies, how costs work, and which suppliers to use can feel overwhelming. Medicare has specific rules about what counts as DME, how much you pay out of pocket, and whether equipment is rented or purchased. Knowing these details upfront can save you hundreds of dollars and prevent claim denials that delay the care you need.

What Qualifies as Medicare Durable Medical Equipment

Not every medical device counts as DME under Medicare. To qualify, equipment must meet all of these conditions. It must serve a medical purpose. It must withstand repeated use over at least three years. It must be appropriate for home use. And a doctor or treating provider must prescribe it as medically necessary.

Common examples of medicare durable medical equipment include power wheelchairs, manual wheelchairs, hospital beds, oxygen concentrators, CPAP machines, nebulizers, walkers, and patient lifts. Glucose monitors and infusion pumps also fall under this category. In most cases, items used solely for convenience or comfort do not qualify. For example, a standard air conditioner would not be covered, even if a doctor recommends it.

Medicare specifically requires that the equipment be used in your home. A hospital or skilled nursing facility does not count as your home for DME purposes. If you move to a long-term care facility, your DME coverage rules may change. Additionally, CMS maintains an official DME reference list that defines covered item categories.

Costs, Rental Rules, and How Medicare Durable Medical Equipment Payment Works

Medicare Part B pays 80% of the approved amount for DME after you meet your annual deductible. In 2026, the Part B deductible is $283. After that, you pay 20% coinsurance on each item. As a result, a Medicare-approved wheelchair costing $1,000 would leave you responsible for $200 in coinsurance, plus any remaining deductible.

Medicare handles DME payment differently depending on the item type. Some equipment must be rented. Some must be purchased outright. Others give you the choice. For capped rental items, Medicare pays monthly rental fees for up to 13 consecutive months. After that period, you own the equipment. Complex power wheelchairs can be purchased in the first month. TENS units require an initial two-month rental period to determine effectiveness before purchase becomes an option.

During the rental period, your supplier is responsible for repairs and replacement parts. Once you own the equipment, Medicare may still cover necessary repairs. Typically, suppliers who accept Medicare assignment can only charge you the deductible and 20% coinsurance on the Medicare-approved amount.

How to Get Covered and Avoid Claim Denials

Getting medicare durable medical equipment starts with your doctor. Your treating physician must write a prescription and, for certain items like power wheelchairs, must conduct a face-to-face examination within six months before the order. This face-to-face requirement exists to confirm medical necessity. Without proper documentation, Medicare will deny the claim.

You must also use a Medicare-enrolled supplier. This is a critical step many beneficiaries overlook. Medicare will not pay for DME purchased from non-enrolled suppliers, regardless of medical necessity. Enrolled suppliers must hold DMEPOS accreditation from a CMS-approved organization and maintain a $50,000 surety bond. You can find approved suppliers through Medicare.gov or by calling 1-800-MEDICARE.

Prior authorization is another factor to consider. CMS requires prior authorization for specific DME items before delivery. As of January 2025, the standard review timeframe is no more than 7 calendar days. Expedited requests take 2 business days. Suppliers with a 90% or higher approval rate may qualify for exemptions from prior authorization requirements. Your local SHIP program can help you navigate prior authorization and appeals if a claim is denied. Organizations like AARP also provide resources for understanding your medicare durable medical equipment benefits.

Frequently Asked Questions

Does Medicare cover all types of durable medical equipment?

No. Medicare only covers DME that is medically necessary and prescribed by a doctor for home use. The equipment must also be durable enough to withstand repeated use over at least three years. Items used for convenience, such as grab bars or raised toilet seats, are generally not covered under medicare durable medical equipment benefits.

Can I buy DME from any medical supply store?

You must purchase or rent DME from a Medicare-enrolled supplier. Otherwise, Medicare will not pay for the equipment. Enrolled suppliers are required to hold DMEPOS accreditation and accept specific billing standards. Check Medicare.gov to verify whether a supplier is enrolled before placing an order.

What happens after I rent DME for 13 months?

For capped rental items, ownership transfers to you after 13 consecutive months of rental payments. During the rental period, the supplier handles all repairs and maintenance at no extra cost. After ownership transfers, Medicare may still cover medically necessary repairs to your medicare durable medical equipment under Part B.
